parasound a31 review

What I mean by this is that a manufacturer of a three-channel amplifier, in this case Parasound, assumes that the customer has an existing stereo amp (or two mono amplifiers) that he or she likes and simply wishes to add amplifier channels for a center channel and surround speakers. Like the Levinson, the 3250e also retails for far more than the A31, coming in at $10,000 as well. Three-channel amplifiers were all the rage a few years ago, but then sort of faded away. I was certain I had owned a Parasound amplifier at one point in my life. On the other hand, the Krell Evolution 3250e has a slightly more spirited sound versus that of the A31, in that the Krell is a bit more dynamic and taut throughout. It’s claimed to provide pure class-A operation up to 7Wpc, high-bias class-A/B operation thereafter, and to deliver 250Wpc into 8 ohms or 400Wpc into 4 ohms, all three channels driven. All Halo products are available in black or silver finish. The rest of my system was as follows: Dune-HD Max and Oppo BDP-103 as the primary source components, Behringer Feedback Destroyer feeding into a single JL Audio Fathom f110 subwoofer with parametric EQ filters from Room EQ Wizard, and a SIM2 Nero single-chip DLP projecting onto a 120-inch Acoustic4K screen from Elite Screens.

While this isn't going to be of much use to 99 percent of those who buy an amp such as the A31, I found it very useful and, as a result, a huge selling point. And despite what the purists say, on occasion, for example when playing a poorly engineered recording, they can be useful. Since its founding in 1981, Parasound has become one of the industry's … There is even a loop out option for daisy-chaining several amps together if you so desire. When more than three channels were needed, it was always paired with my Parasound Halo A21. I recently upgraded my front speakers to B&W 804D3. Parasound Halo A51 Multi Channel Amplifier. It joins the two-channel Halo A 21 and the five-channel Halo A 51 -- only the Halo JC 1 monoblock costs more. Review By Dwayne Carter It's amazing how the mind works. IMO the Parasound is the better amp with a little more of a laid back presentation. To the left of the input options rests a gain knob that gives you control, plus or minus 6dB off normal or THX reference, to help level match the A31 to other amplifiers - presumably ones that fall outside of the Halo lineup of products.

Not to say that these weren't present via the A31, it's just that neither drew attention to itself in a "look at me" fashion. Parasound may have been thinking along these lines when they engaged the well-known amplifier designer John Curl to create their new five-channel amp, the Halo A 52+ ($2,995). While the Halo A 31’s power and bass control were impressive, its midrange clarity and ability to vividly float voices between the speakers at exactly the right depth -- not too up-front or recessed -- rivaled that of much more expensive amps. I set up the Parasound Halo A 31 to drive the three front channels of my reference multichannel system, primarily using an Anthem Statement D2 surround-sound processor to listen to multichannel audio recordings and movies as well as two-channel recordings. Parasound has never offered a three-channel amplifier and, while three-channel amps are nothing new within the industry, fans of the company are probably asking themselves (and Parasound) what took so long. With a claimed power output of 250Wpc into 8 ohms, the A 31 should be able to drive the three front speakers of just about any home-theater system. $3,499.95. The explosion of bells was precisely that - an explosion - and while they may have rocked my room, they never overpowered my ears nor caused fatiguing. Atmospheric scenes had dead-silent backgrounds when required, and dialogue was more than merely intelligible -- it was realistic, and perfectly integrated within the mix, heightening Emily Blunt’s deadpan delivery of some of the film’s most memorable lines. In truth, I never felt as if I was even tapping its full potential, as the resulting sound was effortless. It should be noted that I ran the A31 both as a main amplifier and as a secondary one, meaning I used it to power my mains exclusively, as well as rear channels. Other features that jumped out at me were the track's many snare hits and rim shots, which were rendered with just a bit more detail and nuance throughout, compared to what had been provided by previous amplifiers employed in my system. And when this album’s deep, sustained bass kicked in, the Parasound packed more punch, with a tight concussive quality and extremely low sustained tones. This review will look at the more conventional, yet equally impressive, design from Parasound. I look forward to hearing it in the future. The whole sonic spectrum was (largely) uncolored and sounded wholly natural to me, possessing zero grain, edge or other maladies that would've otherwise spoiled the performance. I installed the A31 along the bottom of my rack with the A21 resting above, though there are three or four rack spaces between the two in order to allow for proper ventilation. Along the far right side of the back panel rests a large master on/off switch as well as a standard AC power receptacle. The entire performance was one of terrific balance and sheer effortlessness. The sides of the A31 are adorned with heat sink fins that feature rounded edges, so as not to cause any physical harm to the customer or installer charged with moving the A31 into its final position. During the numerous battle scenes, the metallic clanking and grinding of robotic exoskeletons, alien mimics, and powerful blasts from automatic weapons were perfectly positioned, while Christophe Beck’s low, pulsing music score effectively filled every bit of the rest of the soundscape.

Although the Parasound has a lower power rating, it sounded more dynamic and visceral with sound effects, yet more refined with the film’s musical score. As for the A31's soundstage, I found it to be fairly three-dimensional, provided the material called for it, meaning it was capable of extending beyond the front baffles of the speakers and further back as well, while the side to side extension was wall to wall and beyond. Parasound has been making their Halo line of amplifiers for years now, mostly without change. The best part of a product like the A31, or any found within Parasound's lineup, is that the reliability is on par with a wood-burning stove. The purpose of a three-channel amp is to bring multi-channel capability to an existing two-channel system. It also utilizes eight beta-matched, 15-amp 60Hz output transistors for each channel. This year they finally added a 3 channel amplifier targeting the home theater crowd that want a single amplifier to drive their front three channels. Each features XLR as well as RCA input options that are selectable via a small toggle switch. It just so happened to not suck and live up to every expectation I had prior to its arrival. As the drummer’s sticks moved across the toms, each stroke differed slightly from the next; the strokes were spaced evenly and precisely between the speakers, closely matching the onscreen placement of the drums. ! Even so, with Edge of Tomorrow it lacked some of the A 31’s weight and depth. Low-level detail was brilliantly fleshed out and, even when I dropped the volume to background levels, the experience didn't diminish, it merely scaled. The A31 retails for $3,000, which puts it square in the mid-fi budget category, for it's not quite Emotiva/Outlaw affordable, but a far cry from Mark Levinson/Krell/Classe/McIntosh/ARC/Pass prices. The gain can also be adjusted by +/-6dB using the Gain Normal/THX knob. Likewise, the bass was incredibly resolute and impactful, and though I have heard a bit more heft from my Pendragons, I preferred the A31's articulation and speed, for I have a subwoofer for brute force. Parasound says that the Halo A 31 was developed in response to the increasing demand for a high-performance, high-power, three-channel amplifier.

Below the input options rest a pair of five-way binding posts, one pair for each channel. item 3 Brand New Parasound Halo A31 Three Ch Power Amplifier Black - Retail $3,500.00 3 - Brand New Parasound Halo A31 Three Ch Power Amplifier Black - Retail $3,500.00. Early in the film, the mostly acoustic version of “Come Talk to Me” was notable for its nicely differentiated mix of voice, piano, acoustic guitar, accordion, electric bass, and deep but taut kick drum. I hate the term mid-fi, as that carries with it a sort of negative connotation that the customer is somehow settling for middle of the road, which the A31 is clearly not. 5.0 out of 5 stars based on 1 product rating. From there, I connected the A31 to a host of different loudspeakers, ranging from my trusty Tekton Design Pendragons to a complement of Jade 1 bookshelf speakers from Wharfedale. As with my first tests, I have heard a bit more low-end oomph, but again, I tend to cross my speakers over at anywhere between 50 and 60Hz (80Hz for bookshelf speakers), so that uber-low bass is going to be dealt with by a sub and is only being pointed out here for evaluation purposes. You get a switchable phono stage, a headphone output and even tone controls. Parasound A52+ Five Channel Solid-State Amplifier Parasound's impressive A52+ is truly faithful to music. Even at reference levels at which I could feel the jarring kick of weapons’ recoil among the frenetic action, there was no discernible distortion: the music and dialogue remained stable and coherent, allowing me to listen at these levels for extended periods without fatigue. I only run a 3 channel home theater and have a Parasound A31 3 channel power amps. If I didn’t already own the Anthems, I’m not sure I’d choose them over the Parasound. If you're an existing Halo customer or simply want to take your two-channel rig to new multi-channel heights, you'll be hard pressed to do better than the A31 sonically, though you can definitely spend more.

Dialogue was always intelligible, arguably more so as a result of the A31's power and resolution as described above. I would say I'm using my system 90% of the time for music. The Halo A 31 is able to drive any speaker you are going to throw at it and not complain, as well as impeccably built and beautiful in appearance." The reader may be somewhat surprised at finding a Parasound product reviewed in Superior Audio.This San Francisco-based company has for years offered well made, good-value products that compete principally with other value-priced marques such as Adcom, B&K … Potencia de salida: 250 vatios RMS x 3 continuo, 20 Hz - 20 kHz a 8 ohmios; 400 vatios RMS x 3 continuo, 20 Hz - 20 kHz a 4 ohmios. I connected the A31 to my Integra DHC 80.2 AV preamp, using individual runs of balanced interconnects courtesy of Monoprice. With every cut I played, there was great pace and musicality in these arrangements for acoustic instruments. Those of you with seven-channel systems can still benefit from a three-channel amplifier, as it gives you the ability to run your front three speakers, while utilizing a pair of stereo amps for your surround and rear channels, which could be lesser amps in terms of power than what is required for your front three channels. Around back, you'll find a host of input/output options, as well as a few features not commonly found on most amplifiers, budget or otherwise. Another benefit of having a three-channel amp over, say, a five- or seven-channel one is that it gives you the ability to selectively power up only certain components when need be, thus saving you money at the meter. For more details on the A31's inner workings, as well as design notes, please visit the A31's product page on Parasound's website. Inherent in the design are high current output (up to 60 amps per channel), and a high slew rate of >130V/µs—these specs alone suggested that the A 31 would work well in my system. They can be switched out of the signal path when not needed, giving a slightly clearer sound. While they were completely functional, they just felt cheap in comparison to everything else the Halo affords you. The only faults I found with the A 31 were the lack of a black finish finish, which has been remedied by a new finish that Parasound is releasing now, and the bright lights on the front of the unit. Y al reducir y plantear la A23 hizo un buen aparato, pero NO es la A21. The A31 is THX Ultra2-certified as well. Parasound has established close and long-term relationships, some spanning more than three decades, with contract manufacturers in Taiwan, which are responsible for the manufacturing. Moving on, I went with an old pop favorite, The Wallflowers' hit "One Headlight" off their album Bringing Down the Horse (Interscope Records). Parasound Halo A23 Stereo Amplifier Review In light of our slow shift toward two channel audio (no, we are not abandoning personal audio), I decided it would be a good idea to start with something basic, like a stereo amplifier. Additional Resources Read more multi-channel amp reviews from HomeTheaterReview.com's writers. Each of the channel inputs are neatly arranged, well spaced and labeled 1, 2 and 3, respectively. There was a richer, woodier character to the double bass in “Linus and Lucy,” from the Vince Guaraldi Trio’s A Charlie Brown Christmas (SACD/CD, Fantasy), and the difficult task of articulating the deepest notes of this instrument was accomplished more precisely. . I'm not suggesting the A31 bests the Evolution 403e, I'm just using it to help qualify (or perhaps quantify) its high-end value. The signal path is direct-coupled, meaning no capacitors or inductors are used anywhere in the signal path, and is capable of full power output down to 5Hz. There are also two large handles, a mains power switch, and an IEC receptacle for the provided power cord. After soliciting some advice here and considering various brands and models, I decided on the Parasound A23. Parasound has a longstanding history when it comes to amplifiers. The question that remains is whether the A31 is any good. That last part is a big deal (for me at least), as I've encountered no other brand that does this free of charge. This track is a little more chaotic in comparison to "Everloving," but even with its more bombastic dynamic swings and high-frequency energy, the A31 never faltered. I suppose I've heard a touch more top-end sizzle, but I'm not certain I'd say the A31 is wrong in its portrayal, as everything simply felt right in its delivery.

Very solidly built, it weighs 65 pounds, and its large case, measuring 17.25"W x 7.6"H x 19.1"D, is the same one used for the Halo JC 1 monoblock, the A 21 stereo, and the A 51 five-channel amps. I suppose as money became tight, people went back to all-in-one solutions, i.e., five- and seven-channel amplifiers or AV receivers. So that is how a three-channel amplifier comes into play. Even at low volume levels, the A 31 took control of my speakers, providing a refined sound that was at once rich and inviting, as well as a precisely defined soundstage. 4 Distinct Product Lines. I even went so far as to use the A31 in conjunction with professional commercial cinema loudspeakers from JBL. From the outside, the A31 looks every bit a Parasound Halo product, clad in its trademark brushed silver facade, though Halo products are now being offered in black, too. The many fins of the large heatsinks that comprise the side panels, and the Parasound logo stamped into the top plate, are all covered in a high-quality, black-anodized finish that gives the A 31 a professional, refined appearance. The many screws securing the top plate slightly protrude and are easily visible, but are not particularly distracting. Although Parasound’s Halo amplifiers have remained essentially unchanged for over a decade, they are still considered to offer outstanding value, even by today’s standards: reference-quality sound for budget prices. It was a certainty; that this house full of speakers, was powered by a big Parasound wholehouse amplifier. 5. The gold lettering is understated, and the red Parasound logo glows to indicate that the mains power is connected. Capacidad de corriente: 60 amperios pico por canal. B-Stock items are … Instead, the amp and drivers seemed to work in harmony. Que es muy buen aparato, que suena muy bien, que es muy digno y honrado. The slightly curved and rounded front panel is a thing of beauty. A couple of years ago, Parasound introduced the Halo A 31 ($3295 USD), a three-channel version of their top-of-the-line stereo and multichannel amplifiers, and the subject of this review. Nonetheless, it is still very much a Curl design, with his customary J-FET input stage, MOSFET driver stage, and beta-matched bipolar-transistor output stage—each arrayed in a complementary configuration, making for a more linear and lower distortion circuit. I'm not suggesting that other amps simply ignore the score but, as with the rest of the performance, there just seemed to be a little more presence to it, lending a grander, more epic touch to the whole sequence. The subwoofers were two Paradigm Reference Servo-15 v.2s. The A 31 also got the better of the eVo6 with two-channel music. Parasound Halo A31 Review. Submit a ReviewContact Editorial Policy About us, Privacy Policy CCPA / GDPR Affiliate policy. The A31, like all Halo-branded amplifiers, is a high-bias Class A/AB amplifier, meaning the first few watts - in this case seven - are delivered in pure Class A fashion before switching over to AB status. Moving from left to right the first thing you'll notice are the A31's massive metal rack handles. Make sense? December 5, 2012 by Chris Heinonen Leave a Comment. Through the A 31, the sound across the front channels was flawless. Andrew Robinson evaluates the A31 to see if it carries on the Parasound name. I was taken aback by the level of low mid-bass articulation that was present, which I found equal to that of its high-frequency performance. (16/44.1 FLAC, Columbia/Legacy) is a little dry, but the A 31 reproduced Nelson’s world-weary voice with a bit of smoothness. The ends of the front panel seem made of plastic, but are well matched, and don’t detract from the A 31’s handsomeness, or the overall impression of outstanding build quality. Parasound has nothing to hide here as these are real numbers supported by A21+'s capability of delivering 60 amperes of current per channel, the ability to deliver this power through the amplifier's full band-width, and a low <0.1% Total Harmonic Distortion (THD) when driving the full audio band (20Hz - 20kHz) at rated power.
